Surface Rh species with three iodine atoms showed a high catalytic activity for the hydrosilylation of terminal olefins. The picture indicates three iodides with an ammonium cation “tent” coordinate to Rh, and the hydrosilylation reaction occurs at the electron-rich Rh site. Next, the intermediate reacts with CO2 coming from the factory with the assistance of an iodide, then the final product silyl carbonate is formed.
